You may also optionally shuffle the final order, which is easily accomplished with this chaining "oneliner" password.split('').sort( I generally use 4, which gives me rougly 48-52 random alphanumeric characters, upper and lower cased. Length is the number of 64 bit words to join. Index % 2 ? curr.toString(36).toUpperCase() : curr.toString(36) Or we could make a fancy generic generator which uses Array.reduce to concatenate multiple random 64 bit words, alternating between uppercasing each stanza: (new BigUint64Array(length)).reduce( We could do this either by just repeating the process twice: console.log((new BigUint64Array(1)).toString(36).toUpperCase() + (new BigUint64Array(1)).toString(36)) However, to make it more secure we also want it to be longer and with mixed upper and lower cases. It should give you a truly random string roughly 10-13 characters long. Here we are generating 1 word with 64 bits of random data, and cast it to a base36 string (0-9 and a-z). So here is some totally random raw material, generated just for YOU, to start with. The idea is the same, we're just utilizing window.crypto instead. Generating long, high-quality random passwords is not simple. However, for reference, I'll show a solution based on an actual CSPRNG. Since you only want passwords 8 characters long, I assume you're not interested in this. Please be aware that Math.random() was never designed or meant to be cryptographically secure. Though, you could solve this by simply concatenating two strings, and then slice it back down to 8 characters again. If you are running in an old browser, or Safari, this might mean (in worst case scenario) you get a shorter password than 8 characters. However, please be aware that different browsers and javascript implementations give different bit depth results for Math.random(). The idea is to cast a random number (in the range 0.1) to a base36 string (lowercase a-z plus 0-9), and then fetch the first 8 characters after the leading zero and decimal point. Real Quick-n-dirty™ Math.random().toString(36).slice(2, 10) Specifies the fully-qualified name of the Java class that provides the Random Password Generator implementation. For example, a value of "alpha:3,numeric:2,alpha:3" generates an 8-character password in which the first three characters are from the "alpha" set, the next two are from the "numeric" set, and the final three are from the "alpha" set.Ī comma-delimited list whose elements comprise a valid character set name, a colon, and a positive integer indicating the number of characters from that set to be included. The value is a comma-delimited list of elements in which each of those elements is comprised of the name of a character set defined in the password-character-set property, a colon, and the number of characters to include from that set. Specifies the format to use for the generated password. For example, the value "alpha:abcdefghijklmnopqrstuvwxyz" defines a character set named "alpha" containing all of the lower-case ASCII alphabetic characters.Ī character set name (consisting of ASCII letters) followed by a colon and the set of characters that are included in that character set. The format of the character set is the name of the set followed by a colon and the characters that are in that set. This is a multi-valued property, with each value defining a different character set. Specifies one or more named character sets. Indicates whether the Password Generator is enabled for use. The Random Password Generator component inherits from the Password Generator Properties The Random Password Generator creates random passwords based on fixed-length strings built from one or more character sets.
